TIGG’s activated carbon wastewater systems allow industry to meet environmental effluent requirements and discharge directly to POTWs or permitted surface waters. In some cases TIGG’s systems are used to recycle wastewater for non potable water applications to lessen demand on local water resources.

Using innovative recycling technologies in vibratory grinding processes. Rinse water from vibratory grinding processes ca be contaminated with heavy metals, oils and, depending on the process, even a variety of chemicals. It cannot be discharged into the public sewer system, and usually requires to be disposed of with specialized waste management companies expensivly. But there are alternatives: Vacuum distillation with VACUDEST evaporators is an economical, resource-friendly method for treating this industrial wastewater. It conditions the vibratory grinding wastewater in such a way that it can be reused in the process.

As devices get smaller and the fabrication plants get larger, the purity of the water required for ultrapure water systems increases. In terms of water reuse, the industry has relatively conservative attitudes towards recycling water for ultrapure water applications, but wastewater is treated and reused for cooling and other less critical purposes. Besides semiconductors, two other silicon-based sectors of the microelectronics industry need large volumes of highly pure water: flat panel displays (FPD) and photovoltaics (PV). Although, both sectors are in the process of maturing we anticipate that the increasing complexity of FPD and PV devices will create demand for even higher purity water.
